SSD vs HDD which is the right one for you?

INTRODUCTION:- 

                                               

                                         Most of the people now buy Laptop for their computing needs  and have to make  a decision  between getting either a SSD(solid state drive) or HDD (hard disk drive) as a storage component. So which one is better SSD or HDD? there is  no straight - forward answer  to this question, it is  based on your  needs and you have to evaluate your decision based on those needs, your  preferences, and of course budget. Even though the price of SSDs has been falling, the price per gigabyte advantage is still strongly  with HDDs. Yet, if performance and fast boot up is your primary consideration and money is secondary, then SSD is the best way to go. Let's get into some technical stuff.   

SSD:- 

                                          The SSD stands for solid state drive. You are probably familiar with using USB memory  sticks, SSD can be thought as a oversized version of the humble USB memory stick. Like a memory stick there are no moving parts in a SSD. Rather, information is stored in microchips.  Conversely, a hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. This difference is what makes SSD so much faster. 

                                          SSD is based on the flash memory.This is a non-volatile type of memory An SSD does not have a mechanical arm to read and write data, The controller is a very important factor in determining the speed of the SSD . The  good controller technology is often what separates an excellent SSD from a good one. An example of a fast controller today is the SandForce SATA 3.0 (6GB/s) SSD controller that supports burst speeds up to 550MB/s read and write speeds.The next gen SandForce 3700 family of controllers was announced in late 2013, and is quoted to reach a blistering 1800MB/s read/write sequential speeds as well as 150K/80K random IOPS. the size of SSD is 2.5

HDD 

             HDD  (Hard Disk Drive) was first introduced by IBM in 1956 - yes guys this is nearly a 60-year old  technology. HDD 's uses magnetism to store data on a rotating  platter. A read/write head floats above the spinning platter reading and writing data. The faster the platter spins, the faster an HDD can perform. Typical laptop drives today spin at either 5400 RPM (Revolutions per Minute) or 7200RPM, though some server-based platters spin at up to 15,000 RPM . 

           The major advantage of an HDD is that it is capable of storing lots of data cheaply. These days, 1 Terabyte (1024 gigabytes) of storage is not unusual for a laptop hard drive, and the density continues to grow. However, the cost per gigabyte is hard to calculate now-a-days since there are so many classes to consider, though it is safe to say that all HDDs are substantially cheaper than SSDs

   When it comes to appearance, HDDs essentially look the same from the outside as SSDs. HDDs predominantly use SATA interface. The most common size for laptop hard drives is the 2.5” form factor while a larger 3.5” form factor is used in desktop computers. The larger size allows for more platters inside and thus more storage capacity. Some desktop hard drives can store up to 6TB of data! . Now it’s time to do some comparisons and determine which might be best for your individual needs - SSD or HDD? The best way to compare items is a table with a side by side by side comparison 

   If these are your following needs then choose HDD  

   

• You need a lot of storage capacity 
• Don't want to spend much money 
• Don't care too much about how fast a  computer boots up or opens programs - then get a hard drive (HDD).                      

If these are your following needs then choose SSD 

•  You are willing to pay for fast performance 
• Don't mind limited storage capacity or  can work around that  

Overall Conclusions:- 

                                              

                                Lately, many people prefer the SSHD option, though, because it does combine the best of both worlds (uses both HDD and SSD features, separately). In most cases, the thing to think about when choosing a drive type is cost-effectiveness.  

 You want to get as much "bang for your buck" as you can when buying a drive because drives aren't cheap. In this reviewer's opinion, the SSHD option is the best choice, since it is the most cost-effective option; combines both HDD and SSD options; and is slim enough to fit into your shirt pocket. Hope this article gave you enough knowledge to make the right choice.
